I have a couple of Trojan T-145's for the house bank. Installed new in June 2001. Anyone want to hazard a guess as to when to replace them, "just because?"
This summer, according to The Plan, we will go up the Washington coast to the rendezvous and then wander the boat around Puget Sound for a few weeks before returning to Oregon and home.
I would hate to have to replace these heavy batteries while out cruising, for equal reasons of convenience and cost.
They have been on "float" on a Statpower 20 shorecharger when at the dock, and do not have many "deep" cycles on them.
Sidebar: I once thought that quality batteries had very very long lives, but my 12 volt Trojan AGM starting battery died last summer. And it was new in 6/01, too. To somewhat reassure the experts, my two types of battery chemistry are not (normally) electrically combined. The AGM lives the life of a hermit, under the aft cabin berth, and waits patiently to start the diesel and accept a 20 minute alternator top-off, and then returns to contemplating its place in the universe.
I realize that there is no precise answer for the house bank question, but still... your collective experiences are always helpful.
